In Australia, koala's are dangerous and are called "Drop Bears". Apparently there was a story I heard about it where British settlers were there and were all like getting log wood and pretty much destroying habitats, and like these logger guys would just disappear and were not coming back or whatever, so everyones like "What the heck, where are they?" so they sent search parties and... They would find them dead from blood loss, next to the trees. Then they would find a koala covered in blood. They apparently like drop from the trees and claw into you with those claws they use to climb the tree bark. I honestly don't like koala's now and um...this is legitimately scary!
